A place some call paradise
Ahh yes happy "korning" everyone. The holidays are past now. I have to go back to work tomorrow and will not have an extended leave until we leave in May. Plus side is that I get to drop the last guest off at the airport in about 80 minutes and I'm not hungover! I guess I found the perfect line last night. Drank enough to say happy korning at 1am (hst) but not enough to be hugging a toilet at 1010. Gonna be a good year.

I need to call on the collective intelligence of the MBV thread (uncle ralphie can chime in too :?:) I'm about to order replacement coils and have a choice between 1.5 ohm, 1.8 ohm, and 2.1 ohm.

What in blue blazes are the advantages vs disadvantages of higher or lower resistance coils?

taste?
longevity?
"my ohms are bigger than your ohms" bragging rights?

The lower resistances are hotter, so juices that tend to burn easily (Tea flavors, for example) wouldn't do well with lower resistance coils. Lower resistance coils also drain the battery more quickly, although it might not be that noticeable. Higher resistance coils don't drain the battery as quickly, run a little cooler, and might not burn as many juices. There are, of course, several other factors that affect your vape. :2c:

All I can tell you for sure is with Kangertech coils I prefer 1.8Ω because they invariably rate at 2.0Ω. When they go above 2.0Ω I just feel like something is missing unless I crank up the voltage really high. My rebuild right now is sitting at 1.6Ω and is pretty great with vapor and flavor at around 3.8v (using a non-mbv juice).

Lower resistance coils seem to heat faster too. So it takes less time before I start seeing good vapor. The downside is battery run time drops. Also, MBV juices prefer 3.3-3.7v range with lower Ω coils or they start picking up a burnt taste. 1.8Ω to 2.0Ω is good for a non-variable regulated 3.7v only device for me.

I have ordered both 1.5 and 1.8 Kanger coils, and they actually read about 1.7-1.8 and 2.0-2.1 respectively. If you are using an ego, or something not variable, the higher resistance coils will be a little anemic IMO. I find the 1.5's (which are actually a little higher) work the best on an ego.

I'm not sure but I think Kanger coils were originally rated using 32 gauge wire, and at some point they switched to 34 gauge and never fixed their Ω ratings to compensate. For me it's really spot on, if I order 1.8Ω they are always 2.0Ω. It is hard to see but I'm pretty sure a stock Kanger head has kanthal that is thinner than the 32 gauge I received from MBV which would suggest a higher gauge is being used in their heads? Of course my eyes are getting old so it could just be they are playing tricks on me.

Taste is certainly a factor. Lower Ohm coils tend to perform better with Thicker and Darker juices. Higher Ohms for the lighter or thinner juices. My battery life increases a bit with higher resistance coils. Your mileage may vary. To see what the impact is on the Wattage and current is, check the Ohm's law calculator. Example 4.2 Volts 2.5 Ohms, we end up with 7.056 Watts and 1.68 amps. 4.2 Volts and 1.8 Ohms, we end up with 9.8 Watts and 2.3333 amps. So you could, on a variable voltage device drop the voltage to a lower setting to get the same amount of Power (watts) applied to the LOWER resistance coils (1.8 Ohm). Your variable wattage device will do this automatically for you. Lower resistance coils also use lower gauge wire, which is thicker and more durable. I have not really seen a significant difference in how long the lower resistance coils last.
When I build my own out of 26 gauge I see a difference in lifespan. They live a lot longer than the 32 gauge stock coils.

I'm using a VTR which is vv/vw and since I'm a bear of very little brain, I don't memorize complicated tables, or plug numbers into ohms the ohms law formula to figure the "sweet spot" .... I simply load up my tank and fiddle with the knob until I get the taste I like and vape on. I guess in my case it really wouldn't matter which ones I got.

You could very well be right, it's been a while since I have ordered Kanger coils. To be honest, I have pretty much abandoned my evods and protanks, but I did always like the lowest resistance coils on a plain ego.

Right, with the VTR it doesn't make much difference. Just dial in the sweet spot and vape away :)

If you ever decide to start rebuilding it might though. I only say this because the thicker the gauge the lower the resistance but the longer it takes for the coil to reach the desired temps. If you're like me and get impatient (as I did this morning) any time wasted waiting for the coil to reach optimum operating temp can be disastrous. :D
